TURBOCHARGER (5.9L DIESEL ENGINE)
A turbocharger is used to force more air into the
engine cylinders. Exhaust gas energy is used to turn
the turbine wheel and shaft. At the other end of the
shaft is the compressor wheel. The compressor wheel
draws air in and forces it into the engine cylinders
through the intake manifold.
Supplying increased air flow to the engine
provides:
• Improved engine performance
• Lower exhaust smoke density
• Improved operating economy
• Altitude compensation
• Noise reduction.
